Which sequence correctly describes one discrete trial?
- AConsequence → response → SD → intertrial interval
- BSD → response → consequence → intertrial interval
- CPrompt → SD → intertrial interval → response
- DResponse → SD → consequence
Show answer and rationale
Correct: B. A discrete trial has a clear beginning (the SD), the learner's response, a consequence (reinforcement or error correction), and an intertrial interval before the next trial. Prompts, when used, are inserted between the SD and the response.
- A — The consequence follows the response, it does not precede the SD.
- C — The SD comes first; the intertrial interval comes last.
- D — The SD must precede the response.
